multibootusb is just too great.

By this year I assume this one has few priority and people who are interested submit PR.

I hope I can contribute to this, but:

• is requiring med lvl linux developer, while I am not.
• I have 0 knowledge on flatpak, but I want to install on arch by flatpak instead of pacman.

@nazar2sfive did the manual installation trouble you? That's the shortcut. Thanks for pointing this one, let see what happen in the future.
